<VV> Rocker Arms

As a participant in this forum, I know that we all have one thing in mind. How can we ensure that our cars are safe and reliable? 

In the welding world, there is more than one way to skin a cat. I know that if you speak to three welding experts about a common problem, (such as cracking), you will get three different opinions about how to solve the issue.

Free speech is what makes this Country great. Now I realize that we all from time to time will have some serious disagreements over a large array of issues. There are some issues that we can never agree on.

That does not make one opinion less valid than the next. 

In this case, obviously all parties are convinced that their position is correct and they are willing to put their business reputation on the line. 

If a customer buys a product from a reputable vendor (of which we have many) and that product fails to perform, it is their loss as I am certain that the customer will vote with their wallet and go to an alternate route on their next transaction. 

I would hope that before making this decision, they would give the vendor the opportunity to make it right. From what I understand, all of our vendors want to make their customers happy.

I have not seen a commercial on TV that has GM saying that Toyota builds junk. Nor does Toyota say GM builds junk. They both promote the merits of their products and services and let the market decide.

Now, I will close in asking for this exchange to stop immediately. Let’s please agree to disagree.

Respectfully, Garth Stapon

RBK - As far as I know, no reputable Corvair parts vendor sells small 
block V-8 rockers to thier customers. The correct Corvair rocker 
assemblies have been easily available to everyone - that is until very 
recently. The only manufacturer of the correct rockers recently told us 
that they were discontinued - but keep in mind that this manufacturer 
has done that before with other parts and after a few months brought the 
part back. Presently we're surviving off of "old" stock that they have 
been locating for us. But....if  the rockers really are discontinued, 
then that will soon come to an end.

Two points - NO, SBC rockers WILL NOT work in Corvair engines. They are 
about 7-8% larger, and the resulting mismatch of geometry will destroy 
the ends of your valve stems. While you may not have  to use rockers 
that are PRECISELY identical to NOS GM, they can't be off by much 
without running into serious problems.

Second, there is discussion about using used rockers. Of course this is 
done all the time. The only issues here involve the general condition of 
the rockers and whether the ball nuts are matched to the rockers. For 
those of us who stay on the ground with our cars, these two points are 
not a matter of life and death because if you use 100 used rockers with 
various degrees of age, wear and mismatched ball nuts you might only end 
up with one or two failures.

But for those who fly with our engines it's a very serious problem, and 
a risk none of them should take. And that is how this whole donnybrook 
about rockers started in the first place - on the Corvair aircraft list.

It's sad that we can now add rocker assemblies to lifters, mechanical 
fuel pumps, brake linings and pushrods in the growing list of Corvair 
parts that have been hammered by bad information. And, thanks to the 
internet, bad information never goes away. Is this good for new Corvair 
owners? Is this good for the Corvair hobby? Don't answer - you might be 
labeled a "troublemaker".    Lon

>First, is there any person or group who is really supporting the SBC rocker arm as a replacement in the Corvair? Please give me those names, especially vendors,  so I can avoid them. I don't want to cast aspersions, but only want to avoid a breakdown should I buy from them, believing I am supporting Corvair vendors who deserve our  business as well as respect.
